[0044] Figure 1 is an exploded schematic diagram of the power supply of the present invention, and Figure 2 for Figure 1 Please also refer to the power supply assembly diagram. Figure 1 and Figure 2 The power supply 100 includes a first cover 110, a circuit board 120, and a second cover 130. The first cover 110 has four first assembly holes 112; the circuit board 120 is locked in the first assembly holes 112 of the first cover 110; the second cover 130 covers the first cover 110, wherein the circuit board 120 is located in a space co-constructed by the first cover 110 and the second cover 130.

[0045] As described above, in the present invention, by simplifying the outer shell of the power supply 100 into two (ie, the first cover 110 and the second cover 130), the redundant shell seams of the appearance of the power supply 100 can be reduced, so that the power supply 100 looks complete.

[0046] As described above, the first cover 110 has a top wall 114 and a pair of first side walls 116 . The first side walls 116 are located on opposite sides of the top wall 114 , and a normal direction N1 of the top wall 114 is perpendicular to a normal direction N2 of the first side walls 116 . Each first side wall 116 is provided with a pair of first assembly holes 112 .

[0047] More specifically, the first assembly hole 112 is disposed at the folded edge 113 extending from the first side wall 116 toward the interior of the first cover 110 .

[0048] The bottom edge of each first side wall 116 also has a first folded edge 117 folded toward the inside of the first cover 110, wherein the normal direction N3 of the first folded edge 117 is parallel to the normal direction N1 of the top wall 114. When the circuit board 120 is assembled to the first cover 110, the circuit board 120 abuts against the first folded edge 117 and the fastener (such as a screw) 150 passes through the locking hole 122 of the circuit board 120 and is locked into the first assembly hole 112 to lock the circuit board 120 to the first assembly hole 112.

[0049] Figure 3 For fan assembly Figure 1 Please also refer to the schematic diagram of the first cover. Figure 1 and Figure 3 Each side edge of the first side wall 116 also has a second folded edge 118 folded toward the inside of the first cover 110, wherein the normal direction N4 of the second folded edge 118 is perpendicular to the normal direction N3 of the first folded edge 117 and perpendicular to the normal direction N2 of the first side wall 116. In addition, each second folded edge 118 is provided with a pair of second assembly holes 119.

[0050] In this embodiment, the fold 113 is independent of the first fold 117 and is formed by further bending the second fold 118, but the present invention is not limited thereto. In other embodiments not shown, the fold 113 can also be formed integrally with the first fold 117 and independent of the second fold 118.

[0051] The second cover 130 has a bottom wall 132 and a pair of second side walls 134, and the second side walls 134 are located at opposite sides of the bottom wall 132. Specifically, the first side walls 116 of the first cover 110 are disposed at opposite sides of the top wall 114 in the normal direction N2, and the second side walls 134 of the second cover are disposed at opposite sides of the bottom wall 132 in the normal direction N4.

[0052] In addition, the second side wall 134 of the second cover 130 is provided with a plurality of third assembling holes 135 corresponding to the second assembling holes 119 .

[0053] When the second cover 130 is covered with the first cover 110, the bottom wall 132 faces the top wall 114, and the second side wall 134 overlaps with the second folded edge 118, and the fastener (such as a screw) 150 passes through the third assembly hole 135 and is locked in the second assembly hole 119, so that the second cover 130 and the first cover 110 are assembled together.

[0054] Please also refer to Figure 1 and Figure 2 After the second cover 130 and the first cover 110 are assembled together, the second side wall 134 covers the side opening of the first cover 110 where no side wall is provided from the outside of the first cover 110 .

[0055] In addition, since there is only the third assembly hole 135 on the second side wall 134 of the second cover 130, and the second side wall 134 covers the side opening of the first cover 110 that is not provided with a side wall from the outside of the first cover 110 and is assembled with the first cover 110 by overlapping the second folded edge 118, the appearance of the power supply 100 of this embodiment is less redundant than the appearance of the conventional power supply, and the integrity of the appearance can make the user feel comfortable in terms of visual perception.

[0056] Incidentally, the first folded edge 117 is further provided with a first auxiliary assembly hole 117a, the bottom wall 132 of the second cover 130 has a second auxiliary assembly hole 132a, and the circuit board 120 has a third auxiliary assembly hole 124. A locking member (such as a screw) 150 passes through the second auxiliary assembly hole 132a and the third auxiliary assembly hole 124 and is locked into the first auxiliary assembly hole 117a to fix the relative positions of the bottom wall 132 of the second cover 130, the circuit board 120, and the first folded edge 117.

[0057] Please continue to refer to Figure 1 , Figure 2 and Figure 3 The power supply 100 further includes a fan 140 assembled in the first cover 110, and the top wall 114 has a plurality of air holes 114a, wherein the fan 140 is disposed corresponding to the air holes 114a. Specifically, the top wall 114 has a plurality of fourth assembly holes 114b, and the fan 140 is correspondingly locked in the fourth assembly holes 114b, and the circuit board 120 is located between the fan 140 and the bottom wall 132 of the second cover 130.

[0058] The fan 140 is configured to dissipate heat generated by the heat source on the circuit board 120 to prevent heat from accumulating inside the power supply 100 and affecting the service life of the power supply 100 and the operation of the circuit board 120 .

[0059] Incidentally, in this embodiment, the connection between the top wall 114 and the first side wall 116 is designed to be in an arc shape, and the connection between the bottom wall 132 and the second side wall 134 is also in an arc shape. The arc shape of the connection makes the corners of the appearance of the power supply 100 present a smooth streamline design. Compared with the appearance corners of the conventional power supply, which are mostly presented in a right angle manner and have a more rigid feeling, the power supply 100 of this embodiment has an arc shape because the connection is processed with a chamfer, presenting a smooth feeling of streamline design, making the power supply 100 of this embodiment more soft in visual perception, making people feel more comfortable.

[0060] In summary, the power supply of the present invention simplifies the outer shell into two covers, and one cover covers the joint structure of the other cover as much as possible, so that from the appearance point of view, it can reduce unnecessary shell seams and has a novel and visually comfortable appearance.

[0061] In addition, the circuit board in the power supply of the present invention is locked to the first cover located on the upper side, providing a novel arrangement structure, and the assembly process is thereby changed, and is convenient for assemblers to perform assembly.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
